Figure 3-7. RAID 60
RAID 60 Characteristics:
• Groups n * s disks as one large virtual disk with a capacity of s *( n -2) disks,
where
s is the number of spans and n is the number of disks within each
span.
• Redundant information (parity) is alternately stored on all disks of each
RAID 6 span.
• Better read performance, but slower write performance.
• Increased redundancy provides greater data protection than a RAID 50.
• Requires proportionally as much parity information as RAID 6.
